COLLABSIBLE rooxn'r '1 UMBRELLA i ilpp lieation filed February The invention: relates to a collapsible pocket umbrella and has for its primary obj eat to provide anumbre'lla of this type which, i when incollapsed condition, is of such smalldimensions as to be capable of being conveniently carried'in a .gentlemans pocket or in a ladys pocketbook or handbag. It is also an object of the invention, to providea collapsible umbrella which issimple in i 5, 930; Serial-1701426365 13 is screwed over plate 2 and tightened by lock-screw 14: (see Figs. 1 and 4').

A slot 15 in disk 10 and a slot 16 in'disk 11 control the rotation of the disks 10," 11 relatively to each other, with, the aid' of a finger 6 which passes through both of said slots. I As is shown in Fig. 1, in the collapsed position of the umbrella the finger 6 passes-through the construction and reliable inoperation, and

can be manufactured at a low=cost.

On the accompanying drawings is shown by way of example a preferred embodiment of the invention. In said drawings,

plate 2 on top ofdisk lO is screwedtight over- 1 the body 5 in s'uch manner as topermit free movement between plate'2 and disk 10 anut ends of the slots further removed from the center of the disks orQplateslO, 11-. Upon movement of the finger6 toward the-center of the plates in the mannerset-forth hereinbelow-,its simultaneously, eflects relative rotation of the two disks in opposite directi0ns,::

ThQSGLIlbSTaI-ZG soiconr nected to the plates10; .11 that uponrelative rotation ofsuchplates fromtliefull line to. the dotted line position: shown in Fig. 1 the: links are expanded or extended first to the position shown atthe upperleft-hand corner of such figure, and finally to the. position indicated in Fig. 10. To this'end, one of the inner two crossed terminal links of each. set of links is pivotally connected with a rivet'24 in the upper plate and the other to a rivet 25 in the lower plate 11 (Fig. 4), the rivets being preferably'located at the corners of the octagonal plates, the two rivets for each set of links being positioned one at a corner of theupper plate and the other at the next corner (to the right or left, i. e. 45removed) of'the lower plate. The plates are provided.

. withthe marginal groovesor rabbets 23 for V 2.8, slightly flattened at the upper part and Q The hinge bodies 5, 6 are enlarged below the 7 plate 11 accommodating the inner .ends of the' links,

7 the. grooves being provided with walls 46" (Figs. 1 andll) adjacent to the rivets 24,

and against which the links'abut when in the openposition, so that the links are held firmly ill-the openposition. The outer ends of the outer links of each setof links may be provided with hemispherical extensions which 7 in the open position of the links cooperate to form a complete sphere for the purpose of ornamentation (Fig. 1).

and'a're providedwith mortises 26, 1 6-into which fit tenons 27 (Fig. 4) of blocks 27 ,27 These tenons have elongated slots 28,

semicircular-at the lower part (see Fig. 7) andhi'nged o'n' pins 29, 29 fixedly positioned between'the wallsof the mortises 26, The

pins 29are'semicircula-r at their lower surface and slightly flattened at their upper surface,

: so that when the umbrella is'in partly collapsed condition (Figs. 2 and 7) thelower circular bounding surface of the slots 28 willv be engaged bythe lower circular surfaces of the pins 29, so that the blocks 27 with their tenons are capable of being rotated about such pins as shown in Fig. 3; whereas when the fiatsurfaces of the pinsand slots will engage each otherand thus prevent rotation of a the blocks 27 which are in this way rigidly held inthe open position. The collapsible staffor stem 30, whichis formed, likethe 1 arms or ribs 1,'of crossed or lazy. tong links,

; ispivoted: at its upper end to the two blocks 27. To insure complete rigidity for the staff 30 when the umbrella has been opened, I provide conical plugs 31,31 which are fixed to. the free ends of leaf springs 32 anchored on the members 5, 6, and which," when the blocks 27 are moved toward each other (Fig. 4) upon opening of the umbrella, are forced into the free space in themortises 26 above'the tenons,:so that the latter are prevented fromv moving upwardly into'the position in which they can rotate about pins 29.

The'links'of the staff 30 are of segment-like. cross-sectio1 1 (Fig. 4) and are pivotally-connected to the outer surfaces of the flat bottom portions of the blocks 27, the latter partly overlapping when the umbrella is in the open br v open position and Fig. 2 which shows the the umbrella is inthe' open position (Fig. 4) I condition as shown in Fig.

. lapsed thelstaif, as indicated above, is turned into the horizontal position about the pins 29.

The socket mountings 33, 33 are attached to the outer surfaces of the lower ends of the first two links of the staff 30 and loosely riveted to the links (see Figs. 2, 4, and 8). Each socket has a pair of seats34 in each of which is positioned a ball 35 provided withan' ear. The cars of balls 35, 35., 35, 35, are loosely riveted to the collapsible arm" supports or 4 (see Figs. 4 and 8 which show the collapsed position). The balls 35 and sockets 33 thus forma universal joint between the arms 4 and staff 30. .The. arm supports or braces 4 are hingedly riveted toflat extensions 'of'special rivets 36 (Figs'l and 4). cone necting the same with the arms 1.

- Curved finger I riveted to the staff 30'and are adapted tobe held betweenthe fingers during. the opening of the umbrella. The staff 30 is provided with a handle. 8, which may be hinged upon a rivet 38 connecting the lowermostfends :of'the bottom two links of the cane. A square slightly conical pin 39 is urged by, a spiral spring 40 into square opening 41 in the bottomtwo links, which openings come into alignment when the umbrella, is opened (see Figs. 2 and.

supports 37, 37 are fixedly 9). 'The extended staff is thus prevented The coveri annular groove 50 on a metal cover 51 and is protected against injury by the latter'by means of. a rubber insert each arm 1 at each hollow rivet 7 except those iiated 36, through which the supports 4 are connected to the arm's.;' The fasteningmay be accomplished; by means of a fibre pin 44 which is attached: to apiece of tape 45 sewn to the covering at'corresponding points and then insertedthrough thehollow rivets 7, the pin 44 beingplaced inthe'horizonta'l position (see Fig. 6). V

' To-open'the umbrella, the staff30 andhandie 8 are swung into thevertical position by pullingon pin 39; two fingers'are-placed on the finger supports37, 37 ,and then'handle 8 is I pulled down, at which moment the staff 30 opens pulling blocks 27, 27 down until the flat surfaces of slots 28 and pins 29 engage each other. The plugs 31, 31 then enter the spaces above the tenons of blocks 27, while the member 6 moves toward member 5 and effects relative rotation of plates 10, 11, whereupon the arms 1 become extended, the covering 12 becoming stretched until the position shown in Fig. 10 is reached. The pin 39 springs into holes 41, 41 thus keeping the umbrella rigid. To collapse the umbrella, the pin 39 is pulled out and the above operations reversed.

Variations from the specific form of the invention disclosed may be resorted to within the scope of the appended claims without departing from the spirit of the invention.
